them are called sulci. Important sulci of the cerebrum include the central or
Rolandic sulcus, the lateral or Sylvian sulcus, the parieto-occipital sulcus
and the Calcarine sulcus. These sulci help to divide the cerebrum into its four
lobes. Given below is a diagram of brain, its functions, detailing the four
lobes and their associated structures. Four Lobes of the Brain Frontal Lobe:
This is the part of the cerebrum that lies directly below the frontal bone. It
is the part that is present directly behind the forehead. It is separated from
the parietal lobe by the central sulcus, and from the temporal lobe by the
lateral sulcus. The frontal lobe is divided into a lateral, polar, orbital and
medial part.
